Move to Chromium 35.0.1916.17.

This is another one of those big commits made of a lot of smaller squashed
commits done in our "next branch".

Some of our tests are broken but pass in Release mode; we are working on
fixing them.

Most of the changes in the code are caused by upstream Chromium changes,
namely:
